On Thursday, May 28th The Rachel Maddow Show will welcome Curtis Melvin, a doctoral student at George Mason University and contributor to North Korea Uncovered, a citizen effort to map one of the world's strangest, most closed, and isolated countries. The efforts behind the North Korea Uncovered project were featured recently in The Wall Street Journal and can be downloaded here*. Mr. Melvin, who also blogs at North Korean Economy Watch, and his colleagues have plotted Kim Jong Il's primary residence, the "Central Luxury House" seen above, as well as Dear Leader's yacht, the Pyongyang Ostrich Farm and a mysterious runway that appears to run through a mountain, shown below.
